Well it makes you think that SL obviously knows something we don't regarding the manner AHH QUADZILLA has achieved some of those times,otherwise they would of removed all of them.
Anybody raced/seen QUADZILLA online EVER?
And weren't the majority if not all of QUADZILLAS times made pretty soon after release?

And Larikun joined 7th Oct has not posted here since 11th Oct when the first patch came out.

I hope the removal of times after inactivity is not the case,that would be very unfair.
It would mean your records would be scrubbed after 10 weeks inactivity if this were true.

I have a theory of what might be the cause of these removals if the non activity isn't the cause,but I'll wait to see if anybody else picks up on it and comments.
